I"m a student trying to recognize electricity. As I learned indigenous school, power is the flow of electrons, however I"m confused about the measure of electricity.

As i learned, voltage is the "pressure" that the electricity, however it"s a bit abstract if I shot to know the bit world and also atomic world. Is voltage the speed of the electron moving, or the variety of electrons relocating in the flow? Electrons room particles, so how countless electrons are relocating in the flow if the flow is $5 extrm V$ or $12 extrm V$?

What led to the various voltage in the atom world in between two points?

What about amps – exactly how do castle relate to voltage?

electricity is the circulation of electrons

Electricity is about a dozen different things, among which is the circulation of charge-carriers, i m sorry in steels is a circulation of electrons. It"s in reality a slow-moving drift of cost-free electrons which are easily jiggling in random directions.

You are watching: What unit measures the flow of electrons?

how many electrons are moving in the flow if the flow is 5 V or 12 V

Voltage isn"t a measure of flow. Existing is.

If 1 coulomb of charge flows past a allude in one second, we say the circulation (current) is 1 Amp. Electrons have a tiny charge. The takes about 16021765700000000000 electrons to comprise 1 coulomb.

If you think that volts as pressure, remember that your bicycle tire has actually pressure in it, also when it"s leaning against your garage wall surface and nothing is relocating (the atoms/molecules in the waiting in the tire may be jiggling thermally a bit however the wait is not flowing anywhere) so a 20000 pascal press tire may have a circulation of 0 nitrogen molecules per second. Similarly, a item of plastic throughout a 9V battery may have actually no electron flowing through it.

Electric present is what go the work.

No, occupational is energy, for this reason you have to involve volts and time and current.

You room breathing in and out ideal now. It probably doesn"t seem like lot work. If your party-mad friend just permitted girlfriend to breath in order come inflate party ballons you"d find that the same flow of air involved much more work.

Electricity is the activity of electron in a conductor.

Not always. Take it for example static electricity.

Voltage is forced to relocate the electron along.

Free electron in steel are currently moving approximately pretty fast. An electrical field (which you can measure in volts every metre) causes electrons in metals to slowly drift in one direction.
